Mix Groovy and Java? [closed]

Question

I was looking for a scripting language for the JVM to speed up application development. I decided to take a closer look at Groovy.

My questions are:

What is your attitude towards mixed Java and Groovy projects?

Do you think it would make sense to write a whole application in Groovy only?

Answer 1

What is your attitude towards mixed Java and Groovy projects?

Seems to work quite well for Grails.

Do you think it would make sense to write a whole application in Groovy only?

Define "makes sense". I think it may for web applications, but not all applications. I would decide on a case-by-case bass. The safest answer is to say "it should be a mix of Java and Groovy."

Since Groovy runs in JDK 6, I'm assuming that it's no less portable than JDK 6 is.

The performance of web apps is often determined by factors such as network latency or database design (e.g. proper indexing) more than raw language speed.
